Ответ:

$x = 9\frac{5}{17}$

Пошаговое объяснение:

$5\frac{9}{17} + (3\frac{5}{17} + x) = 18\frac{2}{17} \\\\5\frac{9}{17} + 3\frac{5}{17} + x = 18\frac{2}{17}\\\\ x = 18\frac{2}{17} - 5\frac{9}{17} - 3\frac{5}{17}\\\\x = \frac{308}{17} - \frac{94}{17} - \frac{56}{17}\\\\x = \frac{308 - 94 - 56}{17}\\\\x = \frac{158}{17}\\\\x = 9\frac{5}{17}$
